[0033] Working principle: When the cylindrical cleaning screen with good sealing performance is used, the material is put into the interior of the screen drum 22 through the feed hopper 8, and the long neck bolt 3 and the thread of the movable plate 2 are rotated, so that the movable plate 2 can drive the processing box 7 and the sealing baffle 9 to move, so that the processing box 7 can be blocked outside the feed hopper 8, and the sealing baffle 9 can be blocked outside the discharge chute 10. At this time, the sealing cover 23 on the fan 11 is covered on the fan 11, which can ensure the sealing of the cylinder 1 and prevent dust from escaping from the feed hopper 8 and the discharge chute 10 and diffusing into the surrounding air to affect the surrounding environment. When the movable plate 2 moves, the ball 6 will move on the supporting plate 5. On the one hand, it can guide the movable plate 2, and on the other hand, it can make the movable plate 2 move more smoothly and labor-saving. Starting the second motor 20 to drive the screen drum 22 to rotate can screen and clean the material. Impurities fall into the interior of the cylinder 1 through the sieve holes of the screen drum 22. While 22 is rotating, the first motor 15 is also started to drive the screw rod 16 to rotate and the circular ring 17 thread, so that the circular ring 17 can drive the cleaning brush 18 to move outside the sieve drum 22, so as to clean the sieve holes of the sieve drum 22, and to prevent the inside of the sieve holes from being blocked by materials and affecting the material screening. After the screening is completed, the sealing cover 23 is opened first, and the fan 11 is started to draw the dust inside the cylinder 1 into the inside of the processing box 7, but the screened impurities will not be sucked out, and the filter screen 12 can filter the dust, and the dust falls into the inside of the dust collecting box 13, which can prevent the dust from being directly discharged when the impurities are discharged, causing pollution, which is more environmentally friendly. The long neck bolt 3 and the movable plate 2 thread are rotated by the above method, so that the movable plate 2 drives the processing box 7 away from the feed hopper 8 and the sealing baffle 9 away from the discharge chute 10, first discharge the impurities, and finally unscrew the screws on the discharge door 21 to discharge the material.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
